Abstract

474,755. Map holders. AUTO AVISO SOC. ANON. May 5, 1936, No. 12691. Convention date, May 6, 1935. [Class 146 (ii)] A device for displaying road maps or charts comprises a strip 6 of paper or other suitable material having a contour of the road thereon and adapted to be wound from one roller 2 to another 3, a driving-roller 7 between the rollers 2, 3 being provided with spikes or teeth 9 which engage perforations in the strip, and being connected to one of the rollers 2, 3 by an elastic rope or the like, the roller 7 being rotated by a worm 15 and worm wheel 14, one of which can be moved to disengage the worm from the wheel. The elastic rope drive allows for slippage to compensate for increasing diameter of the roller 3. The shaft 16 of the worm 15 is driven by hand or motor, and is journalled at one end in a thimble 19 which can be rocked to disengage the drive. Apertures in the strip 6 opposite places of interest on the map are detected by a switch 22 which operates audible or visible signals or both.
